Connect wirelessly to router connected Hard drive

Windows 7 HP Compaq 615, Belkin N+ Router, Freecom 500gb NTFS HDD

I am trying to make a wireless connection to my external hard drive which is attached via USB to my Belkin N+ router. I use the router as the default gateway to the internet and have used the ping command to check I can send to and receive from the router.So far my laptop is not recognising the hdd even though my son on a Mac has had no problem in connecting to it. All offers of help gratefully received.

I own a Belkin N+ and have a WD 320 HDD attached to it. On the Belkin CD is a software package called Belkin Storage Manager which must be loaded on any PC wishing to gain access to the drive attached to the router, it lists the drive as Z:On Belkin N+ unless you give it a name then it will be Z:the name you gave it on Belkin N+. The reason your son's MAC see's it is the MAC finds everything attached to the IP and it essentially is attached to your router's IP table.

Thanks fishbanjo how do i now connect to it as it is not showing in Computer and I can not map the network drive

When you boot into Windows 7 it should mount your drive and show the letter of it in a ballon in the startup taskbar region (generally under the hidden icons there). Mine simply labeled it Z:Network Bamboo on Belkin N+ because all my hard drives are named after bamboo in one way or another, all 3 of my PC's see it when they boot into Windows 7 at Computer. Did not have to do anything special.

The only icon I have in the system tray is the Belkin Storage Manager icon. There are no other related icons. I have rebooted the laptop and tried changing other settings like switching my home network to a work network. All to no avail.
